Water is the source of life, and the quality of drinking water is closely related to people's health. According to the World Health Organization (WTO) survey, 80% of diseases and 50% of child deaths worldwide are related to poor drinking water quality. A quarter of China's population is drinking water that does not meet sanitary standards. "Water pollution" has become China's most important water environment problem.

After years of publicity and popularization of drinking water and health knowledge, people have gradually understood the impact of drinking water quality on human health and paid more attention to drinking water safety, which provides a great market prospect for the application of water purifier products. Household water purifiers are already in use in 95% of households in developed countries in Europe and America, but the domestic use rate is less than 5%. Therefore, there is still a lot of room for development of domestic water purifiers.

At present, the mainstream water purifiers on the market are all split-type, that is, the filters are connected in series through pipelines. Such water purifiers are complicated in structure, bulky, and inconvenient to maintain and replace the filter element. Later, an integrated water purifier with a filter element integrated in a filter cartridge appeared. The integrated water purifier has a compact structure, a small footprint, and is very convenient to maintain and replace the filter element, so it is more and more popular with consumers. However, the previous integrated water purifier cannot automatically cut off the water after the pure water is full, and the water purifier will continue to produce water, which easily causes a large amount of water to be discharged as waste water, resulting in a waste of water resources.

For this reason, the applicant has invented a cylindrical integrated water purifier. This type of water purifier has a flow control base. The water circuit is connected through the flow control base, eliminating the need for complicated and involved pipelines. Favored by users. Due to structural limitations, the current cylindrical integrated water purifier can only produce pure water or pure water (after preliminary filtration, harmful materials are removed, but there are trace impurities). In real life, in addition to the dietary needs of water, users also have non-dietary needs, such as washing fruits and vegetables. There is no need to use pure water at this time (because the process of using pure water will produce wastewater that is several times that of pure water. , Water consumption is relatively high), and the output of pure water is relatively small, which is low in cleaning efficiency and not very convenient.

Therefore, it is necessary to improve the existing cylindrical integrated water purifier and develop a dual-outlet function, so that the cylindrical integrated water purifier can produce pure water as well as purified water, so as to meet the needs of users for food and non-registration. Water needs in many aspects of the diet.

Connected, the clean water outlet 124 is connected with the clean water pipe 22 of the double outlet faucet 20.

In the case that the pure water valve 23 and the purified water valve 24 of the double outlet faucet 20 are both closed. At the beginning, raw water (i.e. tap water or other unfiltered water) enters from the raw water inlet 121, passes through the raw water inlet channel 131, the raw water insertion cavity 117, the raw water inlet pipe 209, the raw water internal channel 503, the water inlet 502, The upper cavity and the water outlet 504 flow into the filter cartridge, enter the primary filter element from the side from the gap between the barrel 21 and the primary filter element 901, enter the central cavity after primary filtration, and then enter the upper end surface of the reverse osmosis filter element 32. The inlet end face enters the reverse osmosis filter element 32. After filtration, a part of pure water enters the pure water production pipe 907, and enters through the pure water passage cavity 221, the first check valve cavity 111, the pure water outlet channel 132, and the pure water outlet 122. In the water storage bucket, the waste water is discharged into the waste water chamber 222. Part of the waste water flows into the purified water outlet channel 134 through the first waste water outlet 205, the first waste water outlet pipe 206, the third check valve 403, and the third check valve cavity 114. The other part of the waste water is discharged to the sewer through the second waste water outlet 207, the second waste water outlet pipe 208, the second plug cavity 116, the waste water outlet channel 133, and the waste water outlet 123. Since both the pure water valve and the water purification valve of the double outlet faucet are closed, when the pure water in the storage bucket is full, the water pressure in the pure water outlet channel 132 will rise, causing the active valve membrane 311 of the control valve 300 to be affected. The piston 313 is driven to move upwards, and the piston 313 presses the driven valve membrane 313, so that the driven valve membrane 312 presses on the end surface of the boss 501 to block the water inlet 502 and isolate the water inlet 502 from the water outlet 504. Prevent the inflow of raw water and achieve the purpose of automatically cutting off water.

Of course, if the reverse osmosis filter element adopts a high flow reverse osmosis filter element, such as a 1000 gallon high flow reverse osmosis filter element, the water storage bucket can be omitted, and the water outlet 122 connected to the water storage bucket can be blocked.

When the user chooses to use pure water, open the pure water valve 23 in the double outlet faucet 20 (the water purification valve 24 is closed at this time). As the pure water flows out, the water pressure in the pure water outlet channel 132 decreases, which is The pressing force of the valve membrane 311 is reduced, the piston 313 moves downwards to release the actuated valve membrane 312, and the water inlet hole 502 is opened, so that the water inlet hole 502 restores communication with the water outlet hole 504 through the upper half cavity, and the raw water can flow smoothly into the filter cartridge It is filtered to continuously produce pure water. When the pure water valve in the double outlet faucet is closed again, as described above, as the water pressure in the pure water outlet channel 132 rises, the control valve 300 will cut off the entry of raw water and stop water production.

When the user chooses to use purified water, open the water purification valve 24 in the double outlet faucet 20 (the pure water valve 23 is closed at this time). Since the purified water outlet channel 134 is connected to the pure water outlet channel 132, the double outlet faucet 20 is opened. In the water purification valve 24, the pressure in the pure water outlet channel 132 will also be reduced, and the control valve will also open the water inlet 502 as described above to resume pure water production. At this time, a part of the waste water produced will pass through the first waste water outlet 205 and the first waste water outlet 205. A waste water outlet pipe 206, the third check valve 403, and the third check valve cavity 114 flow into the purified water outlet channel 134, mix with the pure water flowing into the purified water outlet channel 134, and then flow out from the double outlet faucet. A large flow of purified water is formed to meet people's non-food needs. Of course, after closing the water purification valve 24 of the double outlet faucet 20 again, as the water pressure in the pure water outlet channel 132 rises as described above, the control valve 300 will cut off the entry of raw water and stop water production.

It can be seen from the above detailed description that the present invention has the following advantages:

The cylindrical integrated water purifier realizes both pure water and large-flow water purification, improves the function of this type of water purifier, meets the user's various water needs, and reduces waste water The role of emissions saves water resources and has a wide range of application prospects.
